Debian, Ubuntu, Linux Mint

Or, if you don't want to install third-party binary package you can build it on your own:

# with docker:
sudo systemctl start docker
sudo ./packaging/ubuntu/docker_ubuntu_package.sh # sudo is not needed if your user is in docker group# or directly from ubuntu host if you don't like docker:
./packaging/ubuntu/create_ubuntu_package.sh

For older releases install the dependencies manually and next follow general installation instructions below.

Spotify:

Spotify theme can be also exported from GUI, but if you prefer commandline interface:

./plugins/oomoxify/oomoxify.sh ./colors/gnome-colors/shiki-noble

Also you can normalize font weight with -w argument, see -h for usage.

Spotify theme settings are backed up to ~/.config/oomox/spotify_backup. To undo the changes made by oomoxify, these files can be copied back to their original location /usr/share/spotify/Apps. Spotify can also be reinstalled, which will reset these files as well.
